Should you service or replace?

The replacement of an HVAC system is a substantial investment and though no one wants to take on an expense of this type, there are situations where it can actually be the most efficient and intelligent thing to do. The truth is that your most valuable  appliance will not last forever.  When your existing HVAC system begins to experience certain conditions and events, your most intellectual decision may be to replace.

Service Frequency

More Info

Under normal conditions the outside unit the condensing unit needs too have the coils cleaned once a year for optimum performance.  The inside coil every 2 to 3 years depending on usage.  the equipment should be inspected at least twice a year, more if heavy usage, for algecide, component checks, and operation.

Major Component Failure

More Info

Before spending a lot of money on a major failure , you should look at the replacement cost of new.  New equipment can have up to a 10 yr warrenty and a savings in energy cost from the higher SEER rating develpoped for the newer equipment

Hot and Cold Spots

More Info

Some systems have differences in temperature because of problems in the duct system or a dirty evaporator restricting airflow into that area.  Changes in duct sizes or dampers may also fix the problem.

 Preventative Maintenance

The fallacy of so many is after making a large investment in an HVAC system, they fail to properly maintain the system. For many it is “out of sight, out of mind”, until it fails!!  Although your HVAC is a durable appliance system, it must have proper attention because when they fail, they normally fail in a big way.  Improper maintenance is the reason for most of these failures.

Lower Utility Bills

More Info

Perhaps the single largest reason to do proper maintenance. When your system runs efficiently it means less money for electricity thereby lowering heating and cooling costs. Proper maintenance assists all the components of the unit running with less strain and all parts working together. This reduces wear and in many cases prevents the need for major repairs or replacement of the entire system. 

Life of the Entire System

More Info

With correct maintenance and service a HVAC system can last well over 10 years. Properly maintained systems have been know to last 20 years or more.  The secret to protecting the initial large investement and avoiding another large invest for replacement can literally be the small cost of proper maintenance.

Emergency Repairs

More Info

Proper scheduled maintenance will not only offset costly repairs, but it keeps the technician and thereby the owner aware of pending items that may require attention. This allows for time to get specialty parts ordered and received or even for service at planned times. Also this will offset the larger service bills created by after-hours and call out emergency service. Avoid disruption of business by doing correct service.

Heathy Air

More Info

A properly maintained HVAC system will not only keep your environment cool or warm, but it assists in maintaing air quality. Clean air filters allows better filtration of airborne particulate and when overly contaminated can become a source to putting more of these contaminents in the air. Air cooling is always operating in a moist environment and can beome a breeding ground for mold and mildew spores.  Proper cleaning and service will assist in abaiting airborne allergies by slowing the growth of bacteria.

What About Warranty Parts?

More Info

Do not be misled that having a new system means no service. Not only will your system immediately begin to gather airborne matter that can lead to problems, timely service can discover faulty or failing parts while they are in a warranty period. Claiming “it went out long ago” will not get your parts replaced if they are outside of a warranty period.
